Al. (a) A 480/120 V, 50 Hz single-phase transformer has an equivalent impedance 0.025 12 referred to low voltage side, and the number of turns on high voltage side is 200 turns. Evaluate i. the magnetic flux flowing in iron core, and (2 marks) ii. the equivalent impedance referred to high voltage side. (2 marks) (b) What material is commonly adopted in manufacturing iron core of (4 marks) transformer? Explain why.
